EARLY SPIN ON FILTER ADAPTER
When I restore an early Chevy V8 that used a cannister oil filter, I like to update for a late style spin-on filter. I machine up a ring 3.800” O.D. with a 3.075” I.D., .300” thick. I bore out the block to except it. I’ve used aluminum and bronze and just plan so the top of the ring is the same height as a late 350. I also rethread the adapter mounting holes for a 5/16” bolt. I can then use the late spin on oil filter adapter. I like it better than the oil filter adapter commonly used, and customers do too.
